New rapid testing technique provides growers with more timely information on herbicide-resistant weeds
As instances of resistance to multiple herbicides continue to rise, it is important that growers have the information needed to respond quickly.…

Junglerice has become a significant problem in dicamba-resistant cotton and soybean crops. In Tennessee, for example, it is found in 76 percent of dicamba-resistant cotton fields and 64 percent of dicamba-resistant soybean fields.…
Complaints about off-target movement of dicamba, 2,4-D and other synthetic auxin herbicides persist, despite the introduction of reduced-volatility formulations. One indicator: a survey shows that 30 percent of Nebraska growers believe injury to susceptible soybean crops is caused by off-target movement of dicamba applied to corn.…
Studies show that pH is one of the many factors impacting dicamba volatility. In fact, the EPA now requires a pH of 5.0 or higher in its registration of new dicamba formulations for dicamba-resistant crops.…
Kochia is a highly invasive weed known to be resistant to multiple herbicides. In the Great Plains region, kochia populations have now evolved resistance to dicamba.…
Cultivars of soybean and cotton that are tolerant of dicamba and glyphosate have been a big hit with growers, allowing them to treat broadleaf weeds throughout the growing season – without damaging their crops.…
With the introduction of crops engineered for resistance to the auxin herbicides, concern has soared about unintentional injury to auxin-sensitive crops through off-target spray drift, volatility and spray tank contamination.…
A study featured in the journal Weed Science is certain to keep many corn and soybean growers up at night. Researchers have identified a waterhemp population in Missouri that is resistant to a record-breaking six herbicide mechanisms of action.…
